- Abstract
Industrial development and globalization forces the European Union to reconsider immediate needs for energy production and transport. The study refers mainly to the impact Craiova II Thermal Power Complex has on vector environment - air. Due to the technological process that pollutes the environment, we have monitored some of the physical-chemical parameters of the air, with implications for the ecosystems. The coal waste deposited in various places has a high content of pyrite. The most important environmental pollution problem is oxidation of the pyrite and the generation of acidity. The coal waste is deposited and constitutes an active source of acid (H2SO4) that generates soil contamination at surface, as well as groundwater contamination, endangering ecosystems. Pyrite oxidation results in Fe2+, SO42- and H+. Coal mining drainages are characterized by low pH, a highly varied composition that prevail in high concentrations of sulphate, iron, manganese, aluminum and other toxic and radioactive ions, as well as solid particles in excess. This drainage is one of the oldest problems arising from coal mining.
